JOHN KIEFER, OF HAMILTON, OHIO.

HOE.

SPECIFICATION forming part of Letters Patent No. 230,552, dated July 27, 1880.

To all whom it may concern:

Be it known that 1, JOHN KIEFER, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Hoes, of which the following is a specification.

- My invention relates to hoes having the eye manufactured in a separate piece from the blade.

In the accompanying drawings, Figure l is a front elevation of the blade and eye, with part of the latter in section, and Fig. 2 is a vertical section of eye and blade.

The blade A is out from a fiat plate. At the o r sthe blade is a mortise, D. The eye or ferrule B has a curtain-like flange, F, at its front end, and from the inside of this fiange the tenon E projects inwardly.

The blade fits up under the flange F, as shown, and the mortise D is hooked over the tenon E. If desired, the mortise may be in the flange and the tenon may be formed on the blade.

At the bottom of the ferrule, at the front end, is formed a hook-stud, I, and the blade of the hoe has a hole in it, adapted to admit this stud after the blade is booked at the top, as before mentioned. The stud I is a hook, by reason of the notch M in its under side.

If the stud be bent downward slightly after the parts are in proper position the notch will look over the edge, the blade in the stud-hole, and ,the parts will be locked together, and the device may, in a way, be said to be complete.

In practice I prefer to provide the ferrule with a lip, L, at the back of the blade, in order that the rivet K may be inserted through both lip and blade. While these fastenings act best in combination, I find that they are somewhat eifective when used separately-that is, the stud I may be used to the exclusion of the rivet K, and vice versa.

A bolt, G, passes across the ferrule,as shown, and is adapted to retaina handle placed in the ferrule. If this bolt be tightened the ferrule will be somewhat flattened, and if the hook-stud I has not been bent downward to hook over the blade the squeezing of the ferrule will tend to force the hook downward till it looks firmly on the blade, in an obvious manner. The bending of the hook-stud is thus seen to be really non-essential.

Application filed June 12, 1880. (No model.)

After the hook is forced down to lock the blade, or before it is done, the wedge H may be driven in above it, between it and the upper edge of the stud-opening, and into the handle of the hoe. The lip J upon the stud I may be bent up, as shown, to retain the wedge.

This form of lock is peculiarly solid and substantiahand cannot give way so long as the handle is in the ferrule.

In practice I find that simply driving the handle into the ferrule tends to force the hook down tightly and solidly.

Longitudinal ribs 0 are cast in the ferrule, to prevent the turning of the handle, and to cause more of an up-and-down stretching strain on the ferrule as the handle is driven in. This aids the looking at the hook. Two ribs, one at the bottom and one at the top, as shown, may be used, or one may act alone.

The ferrule should be of a somewhat malleable material, unless the rivet K is depended on entirely for the lower look.

I claim as my invention-- 1. The ferrule B, having curtain-flange F and lip L, combined with the blade A, adapted to engage inside the curtain-flange by mortise and tenon, and to be riveted to the lip L, substantially as set forth.

2. The ferrule B, having curtain-flange F, adapted to engage outside the blade by mortise and tenon, and the hook-stud 1, adapted 1 to engage with the blade by passing through an opening and hooking downward, arranged substantially as set forth.

3. The ferrule B, blade A, curtain-flange F, inside mortise and tenon top-lock, D E, hookstud I, and compression-bolt G, combined substantially as set forth.

4. The ferrule B, blade A, inside mortise and tenon, D E, hook-stud I, andwedge H, combined substantially as set forth.

5. The ferrule B, rib 0, one or two, curtainflange F, blade A, inside mortise and tenon, D E, and hook-stud I, combined substantially as set forth.
